2 Claims.

The present invention relates to a tool and more particularly to a toolfor manually lifting and removing a cylinder head of an internalcombustion engine from its block.

The primary objects of the instant invention are to provide a tool ofthe general character above indicated which is highly eflicient in itsintended use; to provide such a tool which is simple yet rugged andsturdy in construction; to provide such a tool which is light in weight;and, to provide such a tool which is reasonably economical inmanufacture.

Cylinder heads of internal combustion engines are relatively heavy andbecause of their weight and in instances wherein it is necessary toremove one from its block, it is a considerable undertaking andfrequently requires the efforts of two men. Attempts at removal of aninternal combustion engine cylinder head by one person frequentlyresults in injured fingers or thumbs. The tool of the instant inventionis so devised that one person using the same may readily andconveniently remove such a head from its block.

An illustrative embodiment of the invention is shown in the accompanyingdrawing, wherein:

Figure l is a perspective view of a cylinder head of an internalcombustion engine, the tool of the instant invention for removing itfrom its block being shown in dotted lines in its manually disposedposition with respect to the head;

Figure 2 is an enlarged side elevational view of the tool, partly insection, in it manually disposed position with respect to the cylinderhead;

Figure 3 is an end elevational view of the tool; and

Figure 4 is a perspective view thereof.

Referring then to the drawing wherein like parts of the tool andcylinder head shown are designated by the same numerals in the severalviews, an elongated internal combustion engine cylinder head, generallydesignated I 0, is provided with a longitudinally disposed overhanginglip H along one upper length thereof and with a plurality of verticalbolt receiving bores I2, [3 inwardly of the lip ll whereby the head issecured to its block, the bore [3 being disposed medially of the lengthof the head Ill.

The tool per se of the present invention comprises a horizontallydisposed handle I4 to one end of which is secured an open triangularlyformed depending head I5 having a base [6 in parallelism with the handleand a tongue I! depending from the outer end of the head is provided atits lower end with an inwardly triangularly flanged portion [8.

A stud l9 depending at right angles from the 2 inner end of the handlel4 and within the trianularly formed head I5 has a tip portion 20projecting through its base l6 and is of a diameter adapted forinsertion within the bolt receiving bore l3 of the cylinder head Hi.

In use and in instances wherein it is desired to remove a cylinder headII] from its block, the securing bolts, not shown, are first removedfrom their bolt receiving bores l2, l3 after which the tip portion 20 isinserted within the bore l3 and the flanged lower end l8 of the tongueI! is tilted under the lip II of the head III as best shown in Figure 2.

Since the bore I3 i medially disposed with reference to the length ofthe cylinder head Ill and since the handle M of the tool projectsinwardly from one outer length of the head, the head is balanced whenbeing manually lifted from its block and may thus be readily andconveniently removed by one person without danger of injury to thefingers or thumbs of its user.

It will thus be seen that the tool herein shown and described i highlyefilcient in its intended use, is simple yet rugged and sturdy inconstruction, is light in weight and is reasonably economical inmanufacture.

While but one specific embodiment of the invention has been herein shownand described, it will be understood that certain details of theconstruction shown may be altered or omitted without departing from thespirit of the invention as the same is defined by the following claims.

I claim:

1. A tool of the clas described comprising a handle, a dependin headhaving a base in parallelism with the length of the handle, a studdepending from the base at right angles thereto, and a tongue dependingfrom the base at right angles thereto in spaced relation to the stud andhaving an inwardly flanged portion in parallelism with the length of thehandle.

2. A tool of the class described comprising a handle, a depending headhaving a base in parallelism with the length of the handle, a, studdepending from the base at right angle thereto adapted for insertionwithin a vertical bore of an internal combustion engine cylinder block,and a tongue depending from the base at right angles thereto in spacedrelation to the stud and having an inwardly flanged portion inparallelism with the length of the handle adaptedfor engagement under anoverhanging lip adjacent the outer edge of the block whereby the blockmay be removed from its base.
